Task Details/Problem Statements

A. Web Development.

• 1. Design a Interactive Webpage which fetches News using News API
• 2. Design User Interface for a static Blog Website
• 3. A Quiz Web-App using React.js

B. App Development.

• 1. Create a password manager app
• 2. Medicine tracker/ Reminder app
• 3. Food Ordering app

C. Competetive Programming

• 1. It is interesting to find the factorial of a number, and calculating it is also not a big deal. But geeks it is the hacktober fest and you have to calculate the factorial using recursion in any language.
• 2. Given a matrix if an element in the matrix is 0 then you will have to set its entire column and row to 0 and then return the matrix. Try to optimise for time.
• 3. Given two sorted arrays arr1[] and arr2[] of sizes n and m in non-decreasing order. Merge them in sorted order. Modify arr1 so that it contains the first N elements and modify arr2 so that it contains the last M elements. Try to solve with Linear Space Complexity.
• 4. Given a string s, reverse the words of the string. Optimise for O(n) time and O(1) space complexities.
• 5. Given an array of N integers, and a number sum, the task is to find the number of pairs of integers in the array whose sum is equal to sum. Optimise for O(n) time and space.
• 6. Given a String, find the length of longest substring without any repeating character. Try to obtain O(n) time and Space Complexity.
• 7. You are given an array ,find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. The solution should be strictly in O(n).

D. AI/ML

• 1. Face detection logic in any language
• 2. Data Prdeiction Model for any business purchase

E. Blockchain

• 1. Write a lottery smart contract using solidity language
• 2. Write an ecommerce smart contract using solidity language

F. UI/UX

• 1. Design a logo for a Fintech company.
• 2. Design a dashboard page for a tracker app.
• 3. Design a landing page for a portfolio website (generic).
